Problems solved by technology

Its disadvantage is that there are too few ways to choose the ratio of wastewater, there are only two wastewater ratios to choose from, and there is no flushing function. It is not simple enough to use a solenoid valve to realize the opening and closing of the ratio of wastewater

Embodiment 1

[0023] Embodiment 1 is the first implementation of the waste water proportioner of the present invention.

[0024] Such as figure 1 shown. The waste water proportioner includes a valve body 2, which is provided with a water inlet channel 2, a water outlet channel 11, a water inlet chamber 3 and at least two water outlet chambers. The water inlet channel 2 communicates with the water inlet chamber 3 , and at least two water outlet chambers are connected in parallel between the water inlet chamber 3 and the water outlet channel 11 . A water retaining plate 4 is provided between the water inlet chamber 3 and the water outlet chamber, and the water retaining plate 4 is provided with a water outlet hole 5 at a position opposite to each water outlet chamber, and the water inlet chamber 3 communicates with the water outlet chamber through the water outlet hole 5 . A capillary tube can be set in the water outlet chamber to throttle the concentrated water to ensure a sufficiently hi...

Embodiment 2

[0040] Embodiment 2 is the second implementation of the waste water proportioner of the present invention. The function of the wastewater proportional device is generally: 1. Keep the filter membrane with a high enough pressure on the concentrated water side to ensure that the water flows through the filter membrane with sufficient water flow power; 2. Continuously discharge the concentrated water according to a certain flow rate to ensure the water flow. There is a larger tangential flow velocity on the concentrated water side of the filter membrane to prevent the deposition of ions and particles in the water on the surface of the filter membrane and cause the filter membrane to be clogged. The existing filter membrane needs to be cleaned regularly in order to keep it from clogging for a long time. The waste water proportioner in Example 2 is designed to solve the problem of flushing. The difference from the embodiment with three waste water ratio branches in Example 1 is tha...

Abstract

The invention aims to provide a wastewater proportioner which mainly solves the technical problem of low wastewater proportion selectivity in the existing wastewater proportioner. The wastewater proportioner comprises a first wastewater proportion branch, a second wastewater proportion branch, a first control switch and a second control switch, wherein the first wastewater proportion branch and second wastewater proportion branch are arranged in parallel; and the first control switch and second control switch are used for respectively controlling the connecting state of the first wastewater proportion branch and second wastewater proportion branch. By arranging the parallel wastewater proportion branches capable of independently controlling the on-off state, the wastewater proportioner can implement higher wastewater proportion selectivity.

Description

technical field [0001] The invention relates to the field of water purification equipment, in particular to a waste water proportional device. Background technique [0002] The wastewater ratio, referred to as the wastewater ratio, is an important device in reverse osmosis water purifiers and nanofiltration water purifiers. Its function is to make the reverse osmosis membrane or nanofiltration membrane have a high enough pressure in front of the reverse osmosis membrane or nanofiltration membrane by throttling the concentrated water end, so as to ensure that the water flow can pass through the membrane, so as to achieve the purpose of water production. [0003] At present, most of the wastewater ratio solenoid valves in the industry can only set a single wastewater ratio, that is, the flow rate of the wastewater ratio is fixed, and it is impossible to make multiple choices according to the water quality in different regions. In places with poor water quality, insufficient f...
